Can you imagine how hard is to be Samus? Everybody call her "tough", "badass" and "strong". She lives alone, in a spaceship, with no family, friends or even neighbors.

Is she like that by option, or by lack of choice? Either way is a lonely life with no human contact, jumping from one galactic danger to another. Is she fighting to save the universe, or perhaps, to meet her end?

And after Metroid M, she can't really show any emotion (other than being pissed) otherwise Nintendo is "destroying her character".

Can you imagine she deciding to retire, settle down and make a family? No way Samus! It's just Space Pirates for you! No wonder she got so attached to the Metroid, poor girl needs some company...
